I agree, the focus is important. When I first set up my LinkedIn bio I included everything I do. It sounded like the “jack of all trades, master of none”. Not surprisingly, I got little response.

Then I focused on what I really wanted people to know about me. I got specific. And now I get a much better response.

I often tell people that There’s a simple answer: focus on what’s going to be most relevant and impressive to your target reader.

You see, a bio is not a resume. You don’t have to list everything you’ve ever done. Just focus on the parts that are going to “sell” you to your reader.

For example, when I wrote my bio for my site http://www.HowToWriteBio.com, I focused on my technical writing and business coaching background – which is the information that shows that I know what I’m talking about when it comes to writing bios.

Because that’s what potential clients want to know about me in this context. They don’t really care about all the other types of jobs I have held.

A bio is a little advertisement for you. So think about who will be reading your bio and what you want them to know about you. Then advertise your best and most relevant features!

I’ve been amazed at they synergy that comes out of using multiple social media sites. Some people use them all, but many people are seriously loyal to one site. Many people don’t read blogs but are on Facebook every day so clearly that works best for you.

Adding Twitter to the mix just makes sense when you’re on Facebook. I know I frequently find people start following me on Twitter, then I get a friend invite from Facebook then I see their name on my ezine subscriptions. These are people who many never have found me otherwise.

Each site has its best uses. You are absolutely right that the best thing to do is just jump in and start using at least one. That is the best way to learn which works best for your purposes.
